Abstract
The utility model provides a motor driver. A supporting plate is fixed on a fixed bottom shell of a power element, the power element is fixed on the fixed bottom shell of the power element, the fixed bottom shell is arranged on one side of the supporting plate, a driving plate is fixed on the upper portion of the power element, a direct current connection copper bar is fixed on the lower portion of the other side of the supporting plate, one end of a direct current input copper bar is connected with the direct current connection copper bar, and the other end of the direct current input copper bar is arranged on the upper potion of the supporting plate. An insulator is fixed between the direct current input copper bar and the supporting plate, one end of an output alternating current copper bar is connected with the power element, the other end of the output alternating current copper bar is arranged on the upper portion of the supporting plate, and an insulator is arranged between the output alternating current copper bar and the supporting plate. Compared with the prior art, the output alternating current copper bar does not pass through from the position above the driving plate, thereby reducing electromagnetic interference on the driving plate, a control plate and other printed circuit boards (PCBs). The motor driver is convenient to install and maintain, and improves electromagnetic compatibility.
Description
Technical field
The utility model relates to a kind of motor driver, belongs to the Drive technology field.
Background technology
In the electric automobile industry, motor driver is one of critical component of electric automobile.The characteristics such as volume is little, structure optimization, the electric property of motor driver more should at first merit attention motor driver except that satisfying.PCB such as existing motor driver internal control plate, drive plate, because design, its Electro Magnetic Compatibility is relatively poor, installation and maintenance are comparatively inconvenient.
Summary of the invention
The purpose of the utility model is relatively poor in order to solve existing motor driver Electro Magnetic Compatibility, the problem that installation and maintenance are comparatively inconvenient, and then a kind of motor driver is provided.
The utility model comprises that fixedly drain pan, drive plate, power component, output AC copper bar, supporting plate, insulator, the direct current input copper bar of power component are connected copper bar with direct current; Described supporting plate is fixed on the fixedly drain pan of power component; Described power component is fixed on the fixedly drain pan of power component of supporting plate one side, and said drive plate is fixed on the top of power component, and said direct current connects the bottom that copper bar is fixed on the supporting plate opposite side; One end of said direct current input copper bar is connected copper bar with direct current and is connected; The other end of direct current input copper bar is arranged on the top of supporting plate, is fixed with insulator between direct current input copper bar and the supporting plate, and an end of said output AC copper bar is connected with power component; The other end of output AC copper bar is arranged on the top of supporting plate, is fixed with insulator between output AC copper bar and the supporting plate.
The beneficial effect of the utility model: the utility model compared with prior art, the output AC copper bar does not pass through from drive plate top, has reduced to drive plate the electromagnetic interference of PCB such as control board like this.The Electro Magnetic Compatibility that the utility model is convenient for installation and maintenance, improved motor driver.
Description of drawings
Fig. 1 is the structural representation of existing motor driver;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the structural representation of a kind of motor driver of the utility model;
Fig. 4 is that the B of Fig. 3 is to view.
Among Fig. 1 and Fig. 2, Reference numeral 11 is drain pans, the 12nd, and drive plate, the 13rd, control board, the 14th, power component.
Embodiment
To combine accompanying drawing that the utility model is done further detailed description below: present embodiment is being to implement under the prerequisite with the utility model technical scheme; Provided detailed execution mode and specific operation process, but the protection range of the utility model is not limited to following embodiment.
Like Fig. 3 and shown in Figure 4; A kind of motor driver; Fixedly drain pan 1, the drive plate 2, power component 3, output AC copper bar 4, supporting plate 5, insulator 6, the direct current input copper bar 7 that comprise power component are connected copper bar 8 with direct current, described supporting plate 5 is fixed on the fixedly drain pan 1 of power component, and described power component 3 is fixed on the fixedly drain pan 1 of power component of supporting plate 5 one sides; Said drive plate 2 is fixed on the top of power component 3; Said direct current connects the bottom that copper bar 8 is fixed on supporting plate 5 opposite sides, and an end of said direct current input copper bar 7 is connected copper bar 8 and is connected with direct current, and the other end of direct current input copper bar 7 is arranged on the top of supporting plate 5; Be fixed with insulator 6 between direct current input copper bar 7 and the supporting plate 5; One end of said output AC copper bar 4 is connected with power component 3, and the other end of output AC copper bar 4 is arranged on the top of supporting plate 5, is fixed with insulator 6 between output AC copper bar 4 and the supporting plate 5.
Described output AC copper bar 4 is a zigzag.
Described output AC copper bar 4, direct current input copper bar 7 are connected copper bar 8 to be processed by copper plate with direct current, has advantages such as cost is low, processing is simple, is suitable for batch process.
DC master row connects DC cable input dc power; The three-phase alternating current busbar is through power component output output three-phase alternating current; Because the electric current through " Z " font output AC copper bar is bigger, the output AC copper bar does not pass through from the drive plate top, has reduced the electromagnetic interference to drive plate, control board.
Claims (2)
